During a winter's night, the low temperature was recorded at 19oF. The wind-chill temperature that night was -7^oF. What was the difference between the low temperature and the wind-chill temperature?

-26oF

Step-by-step explanation:

The difference between the low temperature and the wind-chill temperature is the result obtained when the low temperature is subtracted from the wind-chill temperature.

This difference

= -7oF - 19oF

= -26oF

The negative sign shows that there was a fall in temperature.

answer:

sometimes

*i think

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
